Abstract |
Laboratory testing of commercially available chemical grouts was conducted to evaluate their potential use, in conjunction with a cheap filler, for remote sealing of mine voids. By close control of the setting time and proper distribution of the grout slurry it was believed that a mine seal could be placed through a borehole from the surface without the benefit of retaining bulkheads. A slurry mix consisting of an acrylamide grout with flyash or mine refuse as a filler was found to produce a strong controllable gel which resisted chemical attack in the laboratory over an eleven week exposure period. An attempt to demonstrate a novel technique for application of the selected grout slurry in a mine entry with high flow was not successful. (Modified author abstract) |
